Analysis of energy efficiency in production lines through the implementation of industry 4.0 technologies

Abstract

Objective: This article aimed to verify the impact of new technologies and concepts of Industry 4.0 on the energy efficiency of the production processes of a company in the automotive sector, an assembly plant. Theoretical Framework: It addresses theoretical contributions on technological innovations in industry, concepts and technologies embedded in Industry 4.0, and technological innovations as a means of improving energy efficiency in production processes. Method: Through the energy consumption generated in the company's production areas and in its lighting system, an analysis of the improvement in energy efficiency was carried out using technologies and concepts prior to Industry 4.0 technologies and an analysis of the energy efficiency of the same environments when possible already using the new Industry 4.0 technologies. With the two surveys obtained, an analysis and comparison of the results achieved was carried out. Results and Discussion: The results demonstrated that there were energy savings and improvements in the energy efficiency of the environments using both technologies, but with Industry 4.0 technologies it became clearer the possibility of maintaining the efficiency achieved and analyzing the data generated. Research Implications: It is crucial to intensify technical updates, improve internet infrastructure and develop public policies that encourage digital innovations. University extension projects focused on technological innovations and artificial intelligence are relevant. Originality/Value: The research provides real data on energy consumption in production areas of an assembly company, highlighting the actions to reduce and improve efficiency in its production processes over time and the technologies used for this action, comparing the technologies used before the advent of Industry 4.0 and after with the use of new Industry 4.0 technologies and their results.
